VERSIONCOMMANDS reply only with ClamAV and database version without the commands list in ClamAV 1.4.1 intermittently

[AThiruna]

We have ClamAV 1.4.1 (clamd service) running on windows VM on Cloud Azure and we are using ClamAV client (https://mvnrepository.com/artifact/xyz.capybara/clamav-client/2.1.2) in our spring boot application which runs on on-premise windows server. Sometimes, we get invalid response exception from ClamAV client since clamd service responds only with clamav and database version (e.g. ClamAV 1.4.1/27502/Sun Dec 29 04:36:30 2024) without the command list for the command VERSIONCOMMANDS.

Able to reproduce the issue by trying to scan the file (InputStream) continuously multiple times. What could be the reason why VERSIONCOMMANDS responds only with their version without the command list intermittently.
