Hi list! |

My virtual server seems to have a problem and I don't know how to find it. |
| 4 |
|

Today, while trying to create a new postgresql database I noticed that |
| 6 |
certain system operations seem to take ages. Normal work on the shell |
| 7 |
works just fine but for example accessing the postgresql server through |
| 8 |
psql, restarting tomcat, postgresql or zope all show the very same behavior: |
| 9 |
Execution freezes, the load average climbs to 1-1.9 and after a few |
| 10 |
minutes (maybe longer) the task finishes correctly. During all this |
| 11 |
time, top reports that the CPUs are 100% idle. |
| 12 |
|
| 13 |
Other services, for example rsyncd or openvpn, work normally. I also |
| 14 |
tried restarting the VM. Shutdown took maybe 10 or 15 minutes. Booting |
| 15 |
was much faster with only a few minutes until all services were up and |
| 16 |
running. However, it didn't solve the problem. |
| 17 |

So, my question is: How can I find out what is causing this? Can I |
| 19 |
somehow trace it? Find out why a process waits? |

Keep in mind that this is a virtual server. I have no control over the |
| 22 |
kernel. Oh, and before you ask: The only recent update was rkhunter from |
| 23 |
1.2.9-r1 to 1.3.4-r2. I also enabled the chkrootkit weekly cronjob. |

Thanks in advance! |
