+Going on to '''protostar''', and issuing '''top''' will let you know if you have processes that seem to be looping:
+
+{{{
+  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
+16618 opensrf   20   0  295m  63m 6104 R  100  0.3  10895:20 apache2
+16223 opensrf   20   0  285m  53m 5120 R  100  0.3 730:36.83 apache2
+16233 opensrf   20   0  283m  53m 5720 R   99  0.3 953:57.18 apache2
+}}}
+
+In this case, we can start by zapping the offending processes:
+
+{{{
+uowadmin@protostar:~$ sudo kill -9 16618
+uowadmin@protostar:~$ sudo kill -9 16223
+uowadmin@protostar:~$ sudo kill -9 16233
+}}}
+
+This should buy some breathing room if nothing else.
