Re: snmpd sometimes does not respond

hi Thomas,

thank you for quick respond.

Altera NIOS I

I could not run ./configure in Microtronix environment (Cygwin based),
I just added new config*.h files which were built for normal Linux, adapted 
them.
Also I created 2 makefiles for agent and snmplib. I can send you them if you 
need.
It works, I have no any broblem, just only one, described here!

> net-snmp run-time configuration? (snmpd.conf and command-line options)
command line is:  snmpd -f -c snmpd.conf
I attached also my snmpd.conf file.

> Details on how you invoke telnetd?
just run it from Windows command line: telnet address

> Details on if/how you query the snmp agent?
iReasoning MIB Browser: Version 4.2

Hope I provided you enough info regarding my environment.

The problem is in packet poiners. It's somehow changed after launching 
telnet, the same problem
happened when I run ps command and try to get some info from snmpd. It's 
looks like something wrong
with file descriptor. When run telnet and close it, I have no any problem. 
But when I just start it and keep
running, then I start MIB Browser get command. Snmpd responded only once. ps 
shows that CPU is growing
up to 100%. snmp is not available after that for mib browser, but it's 
running.
