Hello,

I'm running into some problems with the av_scanner fsecure. In most cases it simply works as expected. In rare cases exim stucks while reading the fsavd socket. As there is AFAIK no way to set a timeout to content scanning, the corresponding exim process will stay runing until it is killed.

Further investigation reveals that fsavd sends "PING\n" messages every few seconds in an endless loop, which don't end the loop in http://git.exim.org/exim.git/blob/HEAD:/src/src/malware.c#l763 . So exim will read again and again the ping.

The f-secure support so far merely states „PING messages are a valid type of reply“. So my questions are:

- Has anyone else experienced this problem and knows a way to mitigate it using a proper config file for F-Secure (I'm using F-Secure Linux Security 10.10).

- Is there a generic way to limit the running time of a malware/spamassassin scan?

Regards
    Michael
