Avaya Support Forums - Buffer Pool 3 dropped below 0

Hello,

Since a couple of years we have a IPO500 v2 with release 8.0(53).
Since the beginning it has random restarts. After the first two times it happend our supplier replaced the IPO hardware with a new one, but restored the software configuration.

After a month, again the IPO had a random restart.
Now, almost 1,5 year later it still has it random restarts. (weekly, monthly)
Sometimes on monday's, sometimes on thursday. Sometimes in the morning, sometimes in the afternoon. Totally abritrary.
At the moment of the restart i'm not doing any mutations. I dont even have the IPO manager open.
And as i said: random. Sometimes on a quiet friday afternoon. Nothing special happening and boom! IPO lost contact. Al the phones in discovering mode and ****** off co workers. :(

With every random restart i see this error in the log: Buffer Pool 3 dropped below 0 - free 144.
Every time the same error.

Now, our supplier doesnt know how to fix it and adviced us to upgrade to Release 9.0.
That is okay, but i doubt that will solve the problem.

What does this error mean?
Is it hardware? Software?

We have a card BRU 4U (9-10) and PRI 2U (9-12) VCM64.

Thanks in advance for at least reading this and hopefully someone can advise me.
