Hello,

I would like to share all findings.

1. Try to remove all unused environment variables to give more memory for command line arguments.
2. Increase ARG_MAX value. Restricted solution since root is required to do that.
3. Use option @file.
4. Use option âspecs=<file>.
5. Use C_PATH and others variables..

In our case option #4 was the best solution.

Thanks,
Vasily.
