Runaway Connection – Connection Timeout

[Tim Malaney]

There are a couple threads on this subject but I don’t see where there are any specific solutions. We have a VPN connection, one of many, that on occasion, times out and begins to file the process log with the following line, 100’s per second. It shots the CPU to 80-100% and files up the log. We have the option in place to limit the log size and an alert that bounces the thread but would like to get to the bottom of the issue. Other VPN connections also time out but recover without the looping. Any suggestions are appreciated.

[pdl :PDL :ERR /0:ADULTMED_RECV:05/04/2012 13:00:07] read failed: Connection timed out

[pdl :PDL :ERR /0:ADULTMED_RECV:05/04/2012 13:00:07] read returned error 238 (Connection timed out)

Tim,

Max Drown posted a stategy that you can use to prevent the timeout here:

Thanks but I don’t know if a keep alive will prevent this. The connection is relatively active. All our other VPN connections timeout and recover – in the first example below. This connection will also do that but on occassion gets into this infinite loop logging the timeout and eating up CPU time – second example..

This is a timeout that recovers

[pdl :PDL :ERR /0:    MCOW_RECV:05/07/2012 08:24:20] read failed: Connection timed out

[pdl :PDL :ERR /0:    MCOW_RECV:05/07/2012 08:24:20] read returned error 72 (Value too large to be stored in data type)

[pdl :PDL :ERR /0:    MCOW_RECV:05/07/2012 08:24:20] PDL signaled exception: code 1, msg device error (remote side probably shut dow

n)

This is th timeout that loops with 100’s of entries/second
