Hi Coders,
I have a problem I have been fighting for a week now. Basically, a
segfault on:
SunOS 5.9 Generic 112233-11 Dec 2003,
NetSNMP 5.4
gcc version 3.2
configure --enable-mfd-rewrites --disable-shared --disable-embedded-perl
--with-mib-modules="if-mib udp-mib tcp-mib ucd-snmp/diskio"
I have noticed the problem only on kernel versions: Generic 112233-11,
and then only a subset of those. Why it works on some and segfaults on
others still alludes me. Patch level on the hosts are exactly the same.
Hardware is V240. Same snmpd build.
The output below is from snmpd running in the foreground with a -DALL
and a truss. I can trigger the segfault by walking anything related to
time. For example, in this case below, my snmpwalk command is:
snmpwalk -v1 -cpublic myhost .1.3.6.1.2.1.25.1.1

I can post a formal bug, but thought I should post the list first.
Thanks for any assistance you can provide.

John
