There was a race between tcpflood and rsyslog in imptpc_maxsessions.sh. We now use the new -A tcpflood option to make the timing more predictable, hopefully fixing test flakiness. Note: if that does not help, we need to introduce a wait on the number of error messages and maybe a delay before tcpflood termination. The theory behind the latter is that rsyslog possibly does not fully iniaitlize session which are quickly aborted before rsyslog receives the related OS notification! We just record this info in case we need it and are positive that this change will fix the situation.
