Dear Tiernan, >> Thank you for the suggested fix. Other than running Minecraft, do you = have any way to reproduce this? >=20 > I've only encountered it running Minecraft, but I'm pretty sure that = anything heavily using libz in a similar fashion (Java or otherwise) = would trigger it because (see below) Or encode PNGs, as my code does. :) >> Also, can you please dig a little to find where you found this? I'd = like to file a bug report for this. If you can't there is no man = overboard, but I like to be thorough. >=20 > After a quick Google I found the source of the patch - = http://www.freebsd.org/cgi/query-pr.cgi?pr=3D154073&cat=3D = <http://www.freebsd.org/cgi/query-pr.cgi?pr=3D154073&cat=3D>; - Although = the fix was actually for the same bug in perl, not Java, hence my = comment above. >=20 > By the looks of it that patch has been MFC'd to 8-STABLE as of the = 21st of July. Thank you for looking this up for me. I installed an 8-STABLE with the fix last night. Interestingly, this = also resolves a problem where I would see excessive CPU usage on the PNG = encoding process. Likely the segfault is related to high CPU usage. I cannot say for sure that this is the case, though. I did a full world = install. -- Kees Jan http://java-monitor.com/ kjkoster@kjkoster.org +31651838192 Human beings make life so interesting.
