[squid-users] "Reserved number of file descriptors" sudden increase

Hello,
 
I'm running squid 3.0.STABLE13 on a CentOS 5.2. It works normally and suddenly it colapsed. In the cache.log appears messages telling run out of file descriptors. Using squidclient I can see a change of this parameter, "Reserved number of file descriptors", from 100 to 1424. Here it is the squidclient info about FD:
 
File descriptor usage for squid:
        Maximum number of file descriptors: 4096
        Largest file desc currently in use: 3193
        Number of file desc currently in use: 2673
        Files queued for open: 0
        Available number of file descriptors: 1423
        Reserved number of file descriptors: 1424
        Store Disk files open: 1
 
Why does that parameter rise from 100 to 1400 in just few seconds? What's going on? Any piece of advise?
 
Regards,
 
Iñigo Rodriguez
