Recently we discovered a memoryleak in our software with a visual basic
component running on a Windows NT 4 platform with service pack 5 and within
MTS 1.0. We are using Visual Basic 5 SP3.
The average CPU load is nearly 50 % (with peaks reaching to 100 %) and the
visual basic component receives approxiomately 1 data-event (containing 4
bytes) each second (with bursts reaching 10 data-events each second). This
visual basic component stores this information internally in a dynamic array
and flushes the dynamic array after each 255 data-events. Therefor it uses
commands like ReDim and ReDim Preserve. Memory leakage is approxiomately 1
MB each hour which results in a crash after approxiomately 3 days.

Has anyone seen similar behaviour in an almost similar environment? or does
anyone know what could cause such leaks?

Stephan
