Hello, My students were recently complaining of firefox crashes and I ran firefox from the terminal and got the message shown below: [milese@server ~]$ firefox -console (firefox-bin:23703): Gdk-WARNING **: shmget failed: error 28 (No space left on device) /usr/lib/firefox-1.5.0.12/run-mozilla.sh: line 131: 23703 Segmentation fault "$prog" ${1+"$@"} I did some digging and it seems to be related to the amount of shared memory (cat /proc/sys/kernel/shmmax returns 33554432). I guess I could increase that amount but I am not sure that will fix the problem ? Any ideas?
