This is a fatal error meaning your system ran out of memory. mod_jk wanted to
get some memory from the operating system to use in a buffer, but the operating
system did not provide the memory. There's nothing mod_jk can do to fix this,
except for logging the error which it did.

You need to check memory usage in your system. Maybe something got slow and
Apache started a lot of child processes finally overloading the system.

If you need to discuss more, please switch over to the Tomcat users list, which
also provides help on mod_jk:

The operating system has a memory 48GB.
Therefore, it seems rather out of memory. 
Should you ever need to specify the settings mod_jk?

Please Help me...
