Having used clamd for several years without it ever crashing, I am now faced with it crashing quite often. This follows me setting up the new sanesecurity system!
I used the old system, before that was stopped, without any problems (I am using 0.94.2). I have written a simple perl script to monitor clamd and re-start it if it crashes because the Sanesecurity signatures are too useful to drop. Th symptoms are quite strange. I am running the fetchsanesigs and freshclam utilities under cron (at different times) and both generally work fine. However, sometimes clamd crashed when freshclam or fetchsanesigs tells clamd to reload. clamd.log shows the 'Reading databases ...' message, but no more. clamd restarts without a problem every time it is restarted. So, it does not look as if there is anything obviously wrong with the Sanesecurity signatures because clamd is happy to load them when it starts. fetchsanesigs uses the USR2 signal, while freshclam connects to the clamd socket to request the reload. Both can cause the crash. It would be nice to be able to log each signature file as it is being loaded, but that does not appear to be simple. It did not work when I put a call to logg() in cli_load() (in readdb.c). Can anyone give me a patch so that I can make clamd log each signature file as it loads it? That way I could see if it always the same file which is being loaded when the crash occurs. Help in diagnosing this would be much appreciated.
