Hi Daniel, I try the sercmd for pkg memory but it return 500 error: # sercmd sercmd 0.2 Copyright 2006 iptelorg GmbH This is free software with ABSOLUTELY NO WARRANTY. For details type `warranty'. sercmd>  pkg.stats error: 500 - command pkg.stats not found sercmd> Is it available only for 3.2.x and master branch? Because we are using 3.1.5. But take the PUA module from master branch for the fetch_row parameter you have patched ;-) core.shmmem is ok. Thanks a lot Laura On Wed, Dec 21, 2011 at 10:58 AM, Daniel-Constantin Mierla <miconda(a)gmail.com>  wrote: _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

Hi Daniel, I just follow the instruction in the link you sent (http://www.asipto.com/pub/kamailio-devel-guide/#c04troubleshooting) to use gdb to print PKG fragments. When I got the error in PUA: Dec 23 11:10:53 /.../sbin/kamailio[23276]: ERROR: pua [send_subscribe.c:158]: No memory left for size:439 Dec 23 11:10:53 /.../sbin/kamailio[23276]: ERROR: pua [pua.c:747]: while building tm dlg_t structure Dec 23 11:10:53 /.../sbin/kamailio[23276]: ERROR: pua [pua.c:652]: while updating record The I run the command gdb /.../sbin/kamailio 23276 and write the following commands in the gdb: set $i=0 set $a = mem_block->first_frag while($i<10000) if($i>2000) if($a->u.is_free==0) p *$a end end set $a = ((struct qm_frag*)((char*)($a)+sizeof(struct qm_frag)+((struct qm_frag*)$a)->size+sizeof(struct qm_frag_end))) set $i = $i + 1 end ... after a while I got a lot of prints on the screen like these: func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1348 = {size = 72, u = {nxt_free = 0x0, is_free = 0}, file = 0x5d76c9 "<core>: parser/parse_rr.c", func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1349 = {size = 72, u = {nxt_free = 0x0, is_free = 0}, file = 0x5d76c9 "<core>: parser/parse_rr.c", func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1350 = {size = 72, u = {nxt_free = 0x0, is_free = 0}, file = 0x5d76c9 "<core>: parser/parse_rr.c", func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1351 = {size = 104, u = {nxt_free = 0x0, is_free = 0}, file = 0x5d76c9 "<core>: parser/parse_rr.c", func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1352 = {size = 104, u = {nxt_free = 0x0, is_free = 0}, file = 0x5d76c9 "<core>: parser/parse_rr.c", func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1353 = {size = 72, u = {nxt_free = 0x0, is_free = 0}, file = 0x5d76c9 "<core>: parser/parse_rr.c", func = 0x5d7b00 "do_parse_rr_body", line = 74, check = 4042322160} $1354 = {size = 72, u = {nxt_free = 0x0, is_free = 0}, ---Type<return> to continue, or q<return> to quit--- ...
