Unable to connect to 7.3.0 DB under load

[Flemming Frandsen]

I have just been running a stress test on a webapplication that uses SAP DB (version: X32|LINUX 7.3.0 Build 029-000-087-800), I use DBD:ODBC compiled against the sapdb driver and the database seemed to keep up nicely except when it had been running for a while then it started to say:

[SAP AG][LIBSQLOD SO][SAP DB]Unable to connect to data source;-709 CONNECT: (cannot create communication semaphore). (SQL-08001)(DBD: db_login/SQLConnect err=-1)

... during connect, it did not work retrying the operation 2 more times.

There were plenty of room until hitting the roof of 200 connections (there were about 30).

Maybe the sapdb client leaks some type or resource?

Has this been fixed in 7.4 and how dangerous is it to upgrade from 7.3?
