By: Roy Sigurd Karlsbakk (rkarlsba) 2006-03-11 13:01:46.000-0600 This crash is with 1.2.0 with a few memleak patches and the sip jb, but it behaves just as badly as 1.2.5, so i guess it's the same. to trigger it, i ran the following commands asterisk -rx 'show memory summary' > logfile asterisk -rx 'show memory allocations' > logfile roy By: Russell Bryant (russell) 2006-03-14 13:16:19.000-0600 Do you think you could be running out of memory? By: Roy Sigurd Karlsbakk (rkarlsba) 2006-03-14 13:54:17.000-0600 nope we have memory monitoring running constantly, and this bug is not related to uptime or free memory By: Russell Bryant (russell) 2006-03-28 13:56:32.000-0600 What architecture is this? I did some work on the trunk to make astmm work on sparc because of unaligned memory access. The backtrace here looks exactly like that. By: Roy Sigurd Karlsbakk (rkarlsba) 2006-03-29 04:25:40.000-0600 This is a dual Xeon64 box from IBM By: Serge Vecher (serge-v) 2006-05-03 12:39:32 rkarlsba: is this still a problem with latest 1.2? If so, please upload a back trace from non-optimized build. Thanks. By: Serge Vecher (serge-v) 2006-05-11 10:10:29 please reopen with new bt if problem persists in latest 1.2 (rev > 26000) without any source modifications please. thank you. | ||
