dsm_sa_snmpd is leaking on the order of 20 Gigabytes per day on a number of Ubuntu 10.04 64-bit systems. I'm seeing this on R905s as well as 2950s. The version of Dell OMSA is 6.0.1-10 and is from the Dell provided Ubuntu package.
The only thing querying Dell SNMP MIB data is the mtk-nagios plugin: http://www.hpccommunity.org/downloads.php?do=file&id=101 I do not see this problem on 32-bit 10.04 running Dell OMSA 6.0.1-10 packaged by SARA. (AFAICT Dell has not yet published a 32-bit Ubuntu package.) I do not see this problem on 64-bit RedHat running Dell OMSA 5.5.0 (packaged by Dell.) Though on this system the 32-bit dsm_sa_snmpd is running. Looking through the archives and other sources, I see reports of memory leaks, but no resolution: http://lists.us.dell.com/pipermail/linux-poweredge/2007-February/029648.html http://lists.us.dell.com/pipermail/linux-poweredge/2007-March/029972.html https://subtrac.sara.nl/oss/omsa_2_deb/ticket/66 I've been strace-ing the processes on the leaking and non-leaking systems. On the leaking systems, the process leaks 94MB over the course of 9194 brk() calls. The pattern is mostly: allocate 1MB, allocate 1MB, free 2MB. However, there are the following leaks: Count Size (Bytes) 11 4096 1 8192 66 12288 385 16384 4 20480 1 24576 1 28672 1 32768 2 65536 1 69632 1 81920 2 90112 2 143360 1 147456 3 1032192 I also see the process calling madvise() on large ranges of memory after it has grown to several GB in size. I don't believe there is source code available. If there is, please point me at it. Otherwise, hopefully the data above will help Dell track down the source of this memory leak. Suggestions and solutions would be very welcome. _______________________________________________ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
