Problem IT10306
|
Status: Closed |
WITH THREAD SUSPENSION ENABLED, CERTAIN MEMORY CORRUPTION CAN CAUSE THREAD SUSPENSION CODE TO INFINITELY LOOP ASSERT FAILING |
| product: |
INFORMIX SERVER / 5725A3900 / B70 - IDS 11.70 |
| Problem description: |
When thread suspension code kicks in, it is possible that while
trying to cleanup memory for the asserting thread, that
non-fatal memory assertions (like memory freed twice errors) can
happen infinitely. There is code in place to make sure looping
signal failures do not occur, but nothing to prevent other
non-fatal asserts. If this happens it will generate huge assert
failure files, and hang the cpu vp that the thread was last
running on not allowing other threads to run, which depending on
the vp can have other negative impacts on the server like
preventing new connections, checkpoints, etc. |
