Issue Number: 700763b
| Issue | When multiple read operations are performed on files under the TBASCFS mount path and those operations are abruptly stopped in bulk, subsequent file access and command execution on the mount path may become unresponsive. |
| Cause | The OS username was being retrieved by executing an external command (whoami) as a subprocess during AS connection. This subprocess triggered filesystem requests to the mount path again, but the TBASCFS worker responsible for handling these requests was waiting for the subprocess to terminate, causing a deadlock and resulting in unresponsive access to the mount path. |
| Solutions | The OS username retrieval was changed to call system library functions directly without executing an external command, preventing deadlocks during mount path access. Additionally, the call was branched to accommodate differences in function interfaces provided in the Solaris environment. |
