"Memory leak in zone VM map entries"?
Hi, all. I have a fairly new iMac (running Catalina, version 10.15.7) and today it's randomly rebooting and I'm getting this error:
panic(cpu 1 caller 0xffffff80125749eb): "zalloc: zone map exhausted while allocating from zone APFS_4K_OBJS, likely due to memory leak in zone VM map entries (1435454160 total bytes, 17472940 elements allocated)"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-6153.141.35/osfmk/kern/zalloc.c:3627
