Suricata

We have been using the unix socket mode heavily in suricata 1.4 to test a large number of pcaps and have previously had no issues.

During testing of suricata2 we started hitting the open file limit and further investigation yielded that suricata does not appear to finish testing the pcaps so never releases the file handles. This has happened consistently regardless of the pcap files tested so we believe it to be an issue inside of suricata. In addition, no alerts are ever written to the log files

The pcap-file-list returns zero in suricatasc

LSOF output from minutes after asking for the pcaps to be tested (normally we have a separate directory per pcap with the same results):
