Hi all, Firstly, I should point out that my knowledge of kernel type things is very limited, so some of this may make little sense.
Firstly, is lpd a multithreaded application? I ask because I'm seeing the occasional runaway lpd process (it's always the queue server process) which I think might be connected with multithreading under Redhat 9. This process uses up close to 100% of CPU time and prevents the queue it serves from doing anything. It will stop doing this if I do an 'lpc kill' of the process. What I see when doing a strace of the process is... [monotype]root: ps -ef|grep 24016 lp 24016 13270 18 May09 ? 07:31:54 lpd (Server) 'bp8' [monotype]root: strace -p 24016 futex(0x42133220, FUTEX_WAIT, 2, NULL <unfinished ...> [monotype]root: .... which some web searching reveals to be connected with NPTL, futexes, multithreading, etc, under Redhat 9, which is where the limit of my kernel knowledge is comfortably surpassed. Has anyone else seen this and, more importantly, can they suggest a fix?
