LONG ANSWER: These are not processes, but threads. There can be up to 13 searchd threads (from which up to ten threads are "working threads" - the threads processing queries, while others are doing some kind of "maintenance"). Number of threads depends on number of search queries users made at the same time (well, _almost_ the same time). Each time searchd super-process finds that there are new search query coming, and all "working" threads are buzy processing another search queries, it spawns a new "working" thread (again, number of "working" threads are limited to ten). Otherwise (there are ten working threads and they are all buzy) the new search query is put on hold (well, in the queue) and will be processed by the first threads that is no longer buzy. SHORT ANSWER: yes, this is NORMAL if you see up to 13 searchd threads. > Some time ago, something strange begins with computer, where aspseek search is >runing. Sometimes system load grows to 150:( Load average of 150 means there are 150 processes (or threads) in "runnable" state in the system. So, to find out if ASPseek is guilty or not, calculate the number of various ASPseek processes in the system: $ ps ax | egrep -c "s.cgi|search|index"If result is less than 150, this is probably not ASPseek whom to blame. As a side note (general, not ASPseek-related) I recommend you to use "top" or "ps" utility to see the processes in "runnable" state and "strace" that processes to find out what the processes in question are doing. > There was 3 searchd processes in memory, and each use 67% of memory... Again, these are not processes, these are threads. Threads _share_ almost all the memory between them, so 67% is the total number, not a number that should be multiplied by the number of threads to get the TOTAL. > So, I disable searchd for few days, and everything was ok.

I mean such programs like ps, vmstat, strace, ltrace, gdb - actually this is a very powerful set. -- -- kir
