[Pkg-nagios-devel] Bug#396337: check_tcp: check_tcp (check_pop) fails on some specific +OK messages

[Benoit Panizzon]

Package: nagios-plugins
Version: 1.4-6
Severity: normal
File: check_tcp


I have a very strange phenomena here. It looks like check_tcp has a boundary problem, being called as check_pop.

If a server answers with this string:
+OK <ad4f481f24925e63234cd40b1438880f at imp.ch>

it get's a timeout.

If the string is slightly longer, example:
+OK <967fd6478ffaf99f8cfb90c0466767b5 at teleport.ch>

it is always successfull.

>From my point of view only the lenght of the return string is relevant to cause this timeout.
Any ideas?
