Hi Maruthi,
Please check the below things:
1. Stop SAP application.
2. Go to /tmp directory.
3. ls -ltr .sapstream*
If you see any files, you can remove them and start SAP and try once.
If possible, you can bounce the OS, then you even do not need to follow the above steps.
Sometime UNIX socket files create issues, as per my experience.
Let us know if you have different location for Solaris.
