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.
