This means that some system call you're making is keeping this semaphore too long. This the the flag that turns on and off the memory protection to the storage heap. Some call in your app is holding on to this too long -- perhaps memory is being reshuffled or there's a really long search routine. I'm not sure. -- Ben Combee, senior DTS engineer, PalmSource, Inc.

Read Combee on Palm OS at http://palmos.combee.net/ I was searching on the net and found that the functions that turn memory protection on and off are MemSemaphoreReserve and MemSemaphoreRelease, but i never used these into my app... These message appear while i'm waiting data from the server using NetLibReceive. Can NetLibReceive be problem?

Is there any way to solve this? You could pre-delete all the records in the database by calling DmRemoveRecord on each one. However, in this case, the warning is erroneous -- it's the OS that's taking too long, not any code of yours. -- Ben Combee, senior DTS engineer, PalmSource, Inc.
