We have an HP LJ4000 on a JetDirect interface, using the foomatic hpijs driver (we want to be able to do PS->PCL conversion on the server for complex jobs). For some jobs (not necessarily particularly complex ones), the job is accepted but stays on the queue with very little happening. Closer inspection shows the socket://... process using close to 100% CPU. Attaching strace it appears to be looping on reads from the socket which return 0 bytes (EOF?).

The error_log output should be enough for the linuxprinting.org
folks to diagnose the problem in Foomatic (i.e. it isn't a CUPS
issue, but a driver issue...)
