Lucido, Probably there should be added a cleaning up of shared memory in code. I experienced the exact same thing in my test VM instance running Fedora release 7 (Moonshine). You can fix this either by a reboot, or by removing still allocated shared memory. If you log in to your server (assuming linux), as root, run 'ipcs' and you will see still sh mem of otrs: # ipcs ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x02a62383 0 otrs 777 1 0 0x02a6231f 32769 otrs 777 4096 0 ------ Semaphore Arrays -------- key semid owner perms nsems 0x00000000 163840 apache 600 1 0x00000000 196609 apache 600 1 0x00000000 229378 apache 600 1 ------ Message Queues -------- key msqid owner perms used-bytes messages The ones of owner 'otrs' can be removed when you are sure apache and otrs is not running. # ipcrm -m 0 # ipcrm -m 32769 I started mysqld, httpd, and otrs services after this and got the good ol' login screen. gr, Frans From: otrs-bounces@otrs.org [mailto:otrs-bounces@otrs.org] On Behalf Of Lucio de Aquino Marinho Sent: zaterdag 25 april 2009 01:37 To: User questions and discussions about OTRS.
