libecap fails every 5 mins and restarts squid

Asked by landysaccount

Hello.

I'm currently testing Squid 3.1.0.14 and have noticed that squid is failing and restarting itself every five minutes. This is what appears in the cache.log:

Could be a bug in the adapter you are using (it shows up at the top of the back trace). Consider contacting the author.

If you think the bug is with libecap or one of the official sample adapters, please provide more info (e.g., the reasons you think the bug is with libecap) and convert this non-question into a bug report. If you think the bug is with Squid, please file a bug report into Squid bugzilla.

Can you help with this problem?
