Hi, I just tried to reproduce this on my system and if you're using "OPEN" and "QUIT" command pairs the opened frontend just won't get closed. I'll take a deeper look at it later...

[vdr] Frequent use of femon leads to "Too many open files", frontend0 file handles aren't closed
Hi, I've encountered a problem with the femon plugin opening /dev/dvb/adapter0/frontend0 and not closing it. While tracking down a different issue I wrote a small script that would periodically (every 30 seconds, say) use svdrp and the femon plugin to grab some information about the current status of my DVB signal. After some hours of this running I discovered VDR would have some weird problems, and I've since narrowed it down to the fact that for whatever reason each loop of my script causes a new opening of /dev/dvb/adapter0/frontend0, which is never closed (even though I do send the femon quit command). I can keep track of how many open file handles there are using "lsof | grep frontend0 | wc", which goes from one open instance at startup to several hundred after hours of running. Ultimately, this causes VDR to stop working since the kernel won't allow it to open any more files beyond a limit. syslog says, as an example vdr: [14876] ERROR (svdrp.c,126): Too many open files last message repeated 175 times Does anyone else see this behaviour, or is it just my setup? VDR 1.6.0, femon 1.6.5, Debian Testing (mostly), Linux 2.6.28.
