[Pw_forum] Restarting ph.x in version 4.0.1

[Eyvaz Isaev]

Dear Deepa,

You can try adding "recover=.true." to your *.ph.in, but it requires saved temporary files.
If this does not fix your problem (one reason is you use parallel environment and temporary files are deleted right after your job stopped or crashed) let me know and I can send you modified files. 

Bests
Eyvaz.
