http://issues.apache.org/bugzilla/show_bug.cgi?id=38403 ------- Additional Comments From [EMAIL PROTECTED] 2006-02-04 12:02 ------- we were unable to ltrace the processes (ltrace returns without error, and sometimes kills the amok process). we found out from looking at /proc, that it is not the allocator_free thread which consumes the cpu, but the core_input_filter thread (telling from the SleepAVG in /proc/PID/status). we recompiled with -ggdb and obtained more infos at the next occurence of the phenomenon. (gdb) info threads 3 Thread -2063254608 (LWP 9309) allocator_free (allocator=0x195737d0, node=0xa52eec0) at memory/unix/apr_pools.c:332 2 Thread 1801628592 (LWP 9350) 0x0807af5b in ap_core_input_filter (f=0x195740b8, b=0x9feddc8, mode=AP_MODE_GETLINE, block=APR_BLOCK_READ, readbytes=0) at core_filters.c:141 1 Thread -1210169664 (LWP 9228) 0xb7f09402 in __kernel_vsyscall () I attach a complete backtrace to this bug. Bottom line is, that we are stuck on this line: ap_core_input_filter (f=0x195740b8, b=0x9feddc8, mode=AP_MODE_GETLINE, block=APR_BLOCK_READ, readbytes=0) at core_filters.c:141 141 BRIGADE_NORMALIZE(ctx->b); code says this: /* ### This is bad. */ BRIGADE_NORMALIZE(ctx->b); but I'm not sure whether "this is bad" refers to a possible bug or just a performance issue. Is there a simple way to inspect the BRIGADE in gdb ? I guess there's a special situation with the brigade or its buckets, that arives from the fact that we run the http-backend on localhost (probably caused by unusual/local tcp behaviour ?) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
