Issue or symptom
When a Palm OS-based device (including handhelds and phones) syncs calendars, it may not sync contacts, or not all information is transferred from the computer to the device during a sync. The iSync log may state that the Palm device unexpectedly disconnected during sync.
Solution
This can occur if the Palm OS-based device runs out of memory during the sync.
Important: If you are using a Palm OS-based Treo provided by Verizon, read iSync: Can't sync Verizon Treo with iSync before performing the following steps.
To resolve this issue, narrow the range of events you've selected to sync with this device. For example, select "Ignore Palm events older than: One Week" if you don't need to synchronize all of your Address Book contacts with your device.
You can also synchronize only a specific group of contacts from your Address Book to save device memory. Create a group in Address Book which contains the contacts you want to sync with your device. Then, select this group from the iSync Synchronize pop-up menu within the Contacts section of the device's setup pane.
If the issue persists, check to see how much available memory is available on your Palm device. If you are low on device memory, you can remove unused applications, photos, sounds or other unused items from the device to free up memory. Consult your device documentation for more information.
On some Palm-based devices, restarting the device (performing a "soft reset") may also free up additional memory or resolve this issue. Consult your device documentation for more information.
