Lotus notes is a very good software, but still a very good software can
have bugs that may cause the software to run unstabale, or incompatibility issues with other softwares or even with hardwares.
After searched the web, contacted with ibm engineers, I have note down
several things that can makes lotus notes to crash.
FYI, I’m using lotus notes, 8.5, 8.5.1 and 8.5.1 FP4.
If you have found that your lotus notes crash many times in a day, you can check the list.
Try to disable your anti virus, if necessary remove it. I know its
extreme, but the are some reports that certain anti virus not very
compatible with lotus notes. If you found disabling anti virus solved the problem, maybe you need to check other anti virus that much more friendly with lotus notes.
Embedded Mime Email
Enable the disable embedded mime email. Its reported that embedded
mime email can crash lotus notes. Thanks to Ying Le Jia for the hint.
Switch to basic version instead of standard version. The Standard version have many features with eclipse, but with more features, it have more possibilities to crash.
Use bottom preview rather then right preview. Its also reported that
right preview pane may cause lotus notes to crash. (anybody can confirm this?)
Adobe Reader 9
If you using adobe reader 9, try to download it to adobe reader 8. Its
reported that after user upgraded their adobe reader to version 9,
their lotus notes start to behave unstable. Thanks to Gunawan TW for the hint.
This list is not completed, will never be completed, because there are still many things that can cause lotus notes (or many other softwares) to crash.
