After installing/configuring the ASM extension, we noticed that after few hours it is consuming default heap memory (1GB) to the saturation level (nearly 100%).
Considering this, we increased the heap memory to 2.5 GB and it reached to the saturation level again.
We are suspecting memory leak issue in the ASM Extension agent (version 20.4).
Observed same behavior in version 20.6 as well where it was consuming 1GB of the default memory.
Due to this issue, the ASM extension stops showing graphical data after a day or so (depending on the heap allocation).
Release : ASM SAAS
Component : Integration with APM
Fixed in latest SaaS hotfix. Customer needs to download the new ASM Agent from the ACC.
