SAP IQ is highly stable. It has been running for years with more data and we have not had any problems.

Early versions crashed frequently. Crashes (IQ freezes for no apparent reason and you have to restart it to resolve it) with the latest versions are rare.

In earlier versions, yes, but not in the past two-three versions.

No issues encountered.

My impression from using the product over its lifetime is a little different than it is now. For IQ 16, the latest, the stability is actually quite decent. It got very, very stable. In the beginning, our implementation was slightly unstable because I changed the network to something similar to Aarna, so there were some issues because of all those changes. It was slightly unstable, but after some adjustments, it's really stable.

Aborts happen, and we don't know why.

With various patches of v15.4 and v16.0, we had instances where the IQ server crashed under certain circumstances. The vendor has addressed most of the issues though.

Not in the recent versions of Sybase IQ.

Sybase IQ is very stable. However, during earlier stages when the server crashes, you need Sybase technical support to help you out.

Very stable. It is an excellent product. We are running it for one of the banks for the last six years. So, in there are the P&L, securities, lending, and borrowing for those business, and we are running it in SAP IQ. No stability issues last I checked.

Not really. In normal functioning SAP Sybase IQ is extremely stable.

Just the stability issues referenced above. A production database server should never crash in response to user input, but Sybase IQ has repeatedly done that for us, over multiple revisions of the product.

No.
