About every 15 minutes or so I get an unexpectedly Quit for a process called PubSubAgent. It only seems to appear on one of the two machines I upgraded, the G% not the G4.

Anyone else seen it, or can tell me what it is. The stack trace looks like a kernal call.


PowerMac G5 2.3G Dual, Mac OS X (10.5)

    Check this thread for more info:

    As noted I've filed a bug report based off this.

    Yep - I'm getting exactly that error too, at around about the same frequency. Started happening a few minutes after upgrading from a (fully up-to-date) Tiger.

    The thread is closed or doesn't exist anymore, wich makes me think it is a known problem with Apple which they don't want to go too public...

    So I guess we will just wait

  • Isaac Ordonez Level 1 (90 points)
    Well then...

    The problem occurs when you are behind a proxy server and:

    A) You have RSS feeds in
    B) You have .Mac Synchronization turned on

    Having .Mac on cases PubSubAgent to crash every ~20 minutes, Having a large number of RSS feeds in can cause PubSubAgent to crash very frequently (every couple of minutes).

    What to do to fix this:

    A) Don't be behind a proxy server
    B) Delete all RSS feeds in and Turn off .Mac Synchronization.

    None of these fixes is really an option.
  • Isaac Ordonez Level 1 (90 points)
    I know, the only real option we have is to wait for apple to release a dot release that fixes this... Here's hoping it is included in 10.5.1...
  • Isaac Ordonez Level 1 (90 points)
    Guess what? 10.5.1 is out... and doesn't fix this issue. Oh well...

    I have the same problem when I'm behind my university's Windows proxy server. Once the PubSubAgent has crashed several times it sometimes remains locked up even when I wake my MacBookPro at home and it's on WiFi without a proxy. The agent then can't be killed via terminal command either.
    Since there is a problem with https handling in Leopard as well which makes Safari (and OmniWeb as well) crash when accessing https sites from behind the Windows proxy server I wonder if this is a symptom of the same problem.
  • David G. Hong Level 1 (0 points)
    I have been experiencing the same problem - I cannot access my work's secure outlook mail server using Safari.

    10.5.1 - doesn't solve the .Mac syncing issue either. I still get the "PubSubAgent quit unexpectedly.." error everytime .Mac sync is on. I disabled it to get rid of it. Mail's RSS is disabled/unused too.
  • Olivier Scherler Level 1 (15 points)
    I had to resort to disabling Privoxy, because in addition to the PubSubAgent crash (that I worked around by turning off bookmark syncing), it makes Safari crash very often when accessing a site that uses HTTP authentication.

    In your Network control panel, enter "" in the bypass proxy settings to fix the problem w/ the PubSubAgent crash. Only works w/ proxy servers that you don't HAVE to go through to access the Internet. Corporate users need not apply...

    You're probably sending HTTPS traffic through Privoxy. Turn off "Secure Web Proxy" to work around the problem with Safari crashing. Again, only works w/ Privoxy or any proxy server that you don't HAVE to go through. Probably a Safari bug -- I use Privoxy for HTTPS (URL's only) and it works fine, but I don't use Safari. Make sure you have the latest Privoxy -- there was a new version (Universal) out a while back.

    This is so frustrating. I get the "PubSubAgent quit unexpectedly error" every few minutes, sometimes every minute or so. It seems like a lot of people are having this problem. I can't even run Mail because it freezes, so I have had to use Entourage since I've upgraded to Leopard.

    Come on Apple, what is taking you so long to fix this?!?
  • DavidEmberton Level 1 (0 points)
    Changing the proxy bypass setting worked for me... thankfully at work our proxy server is set through each computer so I could actually edit the bypass list manually. Very annoying problem though.

    Why is this thread marked as answered? By no means has this been fruitfully answered, or "solved". Hacking network settings is not an "Apple" answer to Apple services like .mac and If my mom couldn't do it without pulling her hair out then it's not fixed. Apple, what gives? This is driving me absolutely nuts!
