Are you using squid as well? You may try doing something like restarting apache. The problem seems related to certain long running processes with fragmented address spaces. Basically, in order to manage address spaces, the kernel keeps track of a bunch of maps. Entries in these maps are stored in... map entries. In certain situations, the kernel can't wait to allocate a map entry, so it grabs one from a static list. Previously, when they ran out, the kernel paniced. Now it just says uh oh. The kernel will merrily go on making more static entries as needed. I'd keep track of how often the message appears. At some point, it should stop. But it's not really alarming, unless it continues to print that continuously.
