That looks like a very busy, if not overloaded, server. You need (at least) to increase the size of your swap to at least double what it is currently set at (either resize partition or add a swapfile.) Here's my sandbox (odd memory size comes from proprietorial hardware, but it's close to yours) running Koha on Ubuntu, with MemCache: $ free -m total used free shared buffers cached Mem: 2379 463 1916 0 82 178 -/+ buffers/cache: 202 2177 Swap: 3999 0 3999 Best - Paul
