Today i updated some packets related to IBM lotus notes and a problem with libraries caused a great and long investigation process to have lotus notes back.
I tried lot of things: reinstalling, purging the packets, installing the same version again... nothing worked. Today i found the solution
here.
It says:
[...] After some research I found the problem: libnuma. If this lib exists in the system the Notes Client loads data forever.
[...] the solution is:
apt-get remove libnuma1
