Adding the right alias...
I have following C program
It takes the DB path as argument
For testing, I have placed the DB on a dir over the NFS
Now after the open call, I unshare the NFS from the NFS server to generate I/O
errors
Once the exec starts receiving errors, it is leaking memory.. after 6 hours,
its leaking upto 1G
I'm using version 3.3.9 and I see the same with version 3.6.23
Any help will be appreciated!
thanks,
