[crit] (28)No space left on device: mod_rewrite: could not createrewrite_log_lock

Hello,

Randomly my Apache server shuts down and won't start:

[crit] (28)No space left on device: mod_rewrite: could not create
rewrite_log_lock

It is easy to fix:

No space left on device: mod_rewrite: could not create
rewrite_log_lock

in your Apache logs or when Apache fails to start, try the following;

ipcs -s

.. Semaphore Arrays ...
key semid owner perms nsems
0×00000000 327680 nobody 600 1
0×00000000 1540097 nobody 600 1
0×00000000 6225922 nobody 600 1
0×00000000 9175043 nobody 600 1
0×00000000 9306116 nobody 600 1
0×00000000 10027013 nobody 600 1

If you see more than 5 of them, you may need to clear them with the
following command;

ipcs -s | perl -ane '/^0x00000000/ && `ipcrm -s $F[1]`'




However I would like to solve this problem for good. Apache has been
running perfectly for 2 weeks with no problems, but suddenly the
problem appeared again.

Any suggestion?
