Load balanced router hangs

Hello,

did anybody else also experience the following problem?

Problem:

The router of a load balanced service object sometimes and all of a sudden stops forwarding incoming requests to its instances, although all instances are available and free.

This finally causes the whole application to hang, since no further call to a method of that service object is being processed.

Observations:

The dump of the load balanced router during this situation indicates that none of the instances is being used (see below). Besides, the instrument MembersInUse has a value of 0.

CPU load of the nodemgr and the router process increase significantly.

There is no DB deadlock.

We have had this problem on several different load balanced service objects (at different times; with dialog durations message or transaction).

It does not depend on overall system load or on available memory resources - the problem can occur at any time.

We can solve this lock situation by restarting the router.

UDS 5.0.3, HP-UX 11

Thanks in advance for any help or hints on what may be going on.

Martin.

We used to have a similar problem on Solaris a while ago.

We found out that our company's security scans of our servers was giving our partitions problems. We suspended the security scans and I don't think we've seen the problem since.

We initially noticed the problem with 5.1.x partitions because there were some useful messages in the log files. However, later I found out that it was also affecting our 5.0.24 partitions but without the errors in the log files.

If you think your servers are the subject of security scans (or even hackers), I can provide some more information.

Hi Mark,

thank you for your response. I talked to our network group, they told me, that there should be no scans going on. Do you have an idea how we could verify this from the application side, e.g. are there any trace flags we could enable to get some feedback?

Anyway, we did further investigations and found the following:

1) The nameservice contains references to old, non-existing partitions, even to partitions that lived before the last reboot of the system, which are not marked as "[Needs Rebind] [Rebinding]" (showpart in nameservice). By the way, the instrument DeleteOnCommFailure is set to TRUE in our environment.

2) The directory $FORTE_ROOT/tmp containing the unix domain socket files does not get cleaned up. It contains even very old entries.

3) Putting 1) and 2) together, we found out that during the hangs of our system, the load balanced router tries to send a message to one of the not-more-existing instances of the Service Object.

Example:

The following dumps were done while our system was hanging.

The router partition in question is ...:0x3ce25:0x1.

The non-existing partition of the Service Object instance is ...:0x3b913:0x2.

The non-existing process has the PID 16736 (there was such a process running a Service Object instance prior to rebooting the system).

The socket file '/forte/tmp/FORTE_A00004160' still exists.

An extract of 'showpart' on the nameservice agent:

I don't know about any trace flags that would help diagnose security scan/hacker related problems. As I said earlier, with Forte 5.1.x we got messages in the logs that indicated a problem. Here's an example:

Task 6: ERROR: qqcm_Hose::ReceiveComplete: Bad packet length 2048 after 16 bytes read of 2048 possible. Packet is corrupt or not from a Forte partition. Make sure no one is attempting erroneous connects to this location: Internet Location - Host: hostnamePort Number: xxxx Dot: xxx.xx.xxx.xx

However, we didn't get any useful error messages in the Forte 5.0.x logs.

It sounds like you may have a different problem.

Good luck.
