[Serusers] quiting immediately

Hi everybody, I got a problem with launching ser. It launch correctly, but quit immediately without prompting an error message. I took a look in the /var/log/messages file and there is what I found: ser: INFO: SIGCHLD received: we do not worry about grand-children ser: DEBUG: tm_shutdown: releasing timers ser: DEBUG: tm_shutdown : removing semaphores ser: DEBUG: tm_shutdown : done ser: shm_mem_destroy ser: destroying the shared memory lock This computer is running SuSE 9.1 with ser 0.8.12 and this problem wasn't there last week. It just appeared today. Since I'm not the only one working on this computer, something could have been modified, but I'm wondering what... Cyprien
