[torquedev] Memory leak in pbs_mom Steve Snelgrove Wed Nov 14 00:06:58 2007
There has been a report of a memory leak in pbs_mom. This becomes noticeable after running many thousands of jobs.
Running some tests with valgrind point to a problem in catch_child.c, post_epilogue.
==12438== 317 bytes in 4 blocks are still reachable in loss record 14 of 29 ==12438== at 0x4021AA4: calloc (vg_replace_malloc.c:279) ==12438== by 0x807BB7D: attrlist_alloc (attr_func.c:316) ==12438== by 0x807BC21: attrlist_create (attr_func.c:378) ==12438== by 0x807ADDB: encode_size (attr_fn_size.c:201) ==12438== by 0x806308C: encode_used (requests.c:1981) ==12438== by 0x804CE80: post_epilogue (catch_child.c:1040) ==12438== by 0x8078063: scan_for_terminated (mom_start.c:459) ==12438== by 0x805FE2E: main (mom_main.c:5756)In this routine, post_epilogue, the variable preq is used twice with alloc_br and does not seem to have corresponding invocations of free_br.
The other routines in this file that are similar, all seem clean up preq with the following sequence of code.
free_br(preq); shutdown(sock,SHUT_RDWR); close_conn(sock);I am still new to this code and am wondering if someone with more experience could look at this and see if this is a problem.
Thanks, Steve _______________________________________________ torquedev mailing list [EMAIL PROTECTED] http://www.supercluster.org/mailman/listinfo/torquedev
