Opened: Jun 11, 2018 Severity: 3-Major
The memory footprint of big3d increases.
Escaped characters are mishandled. This causes the regex compilation to fail and leak memory. The monitor marks the server it is monitoring UP as long as the server returns any response.
GTM monitor recv string such as the following: ^http\/\d\.\d[23]\d\d
If you notice big3d memory footprint increase and you have a monitor recv string that has escaped characters such as '^http\/\d\.\d[23]\d\d', try changing the recv string to something similar to the following: ^HTTP/[0-9][.][0-9] [23][0-9]{2}
Fixed handling of escape characters. Recv strings that previously failed to compile will now compile.
