# 419 Problem with Accessing Multiple In-Memory Tables from Multiple Threads

when I have multiple threads running and I am stressing the limits, it just bombs out with random errors now. I often get 'Rules.idx' is not the correct version, or 'Field doesn't exist'. I even get 8708 on
non-datetime fields, although it is far more likely to occur on tdatetimes.

Comments

Sean's problems were all related to queries being run on in-memory tables in multiple threads along with updates occurring at the same time. The DBISAM engine was not handling shared file positioning properly internally, and this accounted for the random errors.

Resolution

Fixed Problem on 5/25/1999 in version 1.14 build 1
