Hi, I've searched the Apache and Debian mailing lists and generally googled for information about this problem, but came up empty. I'm using apache2 (mpm-prefork) on Debian testing on two different ia32 machines, with generally similar installs, and exhibiting the following problem only on one of them (which complicates the problem, in my analysis). Namely, apache2 won't start if I include the following line in my 'apache2-modssl.conf' file: SSLSessionCache shmcb:/var/log/apache2/scache(512000) I get the following error in my logs: [error] Cannot allocate shared memory: (22)Invalid argument I've read reports on the mailing list of a similar error where it cannot allocate shared memory as the cache file named in Apache's "SSLSessionCache" already exists (but then it said "File exists" rather than "Invalid argument"). In those cases (generally from unclean shutdowns) it appeared that the solution was easy: just manually delete the file. In my case, the file doesn't exist, and I'm getting the "Invalid argument" error. Note also, that I've properly installed the Debian libmm13 package (upstream: OSSP mm), which appears to be necessary for properly functioning shmcb, even though this doesn't seem to be widely documented. I've also tried to decrease the amount of requested memory, going as low as 64000, but all to no avail so far. Any suggestions, please? Thanks, Daniel -- Daniel A.
