System resource exceeded

The STB_MedB laptop gets the following error when sending:

Mirosoft Access - System resource exceeded

Internally this is also noted in the dbengine object as error number 3035.

The laptop has a larger than usual number of records on it, but it is possible to send the data from Tina's laptop at HSC; although it turns out there are intermittent errors there as well.

Observation - Timing of this becoming a problem again

Pagasa observed that this became a problem again around the same time we changed the schedule of PHI Loader.accdb. We discussed possible connections but could not think of anything causal. Just putting this down here in case someone else can think of the connection. Ttenbergen 15:34, 2019 September 12 (CDT)

Solution approach: Query size limiting

The error happens when trying to run Query send check centralized is owner. That query actually ties into the Centralized data.mdb's L_Log. This makes for a very large record set, and have a max size of 1GB rather than the general Access limit of 2GB.

• 13:29, 2019 September 4 (CDT) - optimized the query further, seems to eliminate error for now.

Solution approach: disconnecting wifi

Darryl from STB desktop had suggested that turning off wifi might fix this problem. Since they don't actually have wifi in their area this is easy to try. This worked during his tests, but they have had additional problems sending after that.

During additional tests at HSC Tina found out that sending is faster with wifi disabled, so she added some lines to the sending code that disconnect wifi at the start of sending.

Solution approach: Maxlock setting

• https://access-programmers.co.uk/forums/showthread.php?t=285553 sugggests to apply the following
  • DBEngine.Idle dbRefreshCache
  • DbEngine.SetOption dbMaxLocksPerFile, 1000000

Tried, doesn't solve the problem

Solution approach: Mirosoft Hotfixes

  • Hotfix is no longer available, suggests we use newer software.
  • confirmed this is not installed

Noticed that we may not be getting Office updates installed (newest not present)

Status

As of 09:48, 2019 September 4 (CDT) this is still a problem, and recently more of a problem.

Next things I will try:

• try to send from local to local - the query works fine when I run it while connected to a local version of CFE
• sending again this morning to find out if wifi is still being turned off successfully - Wifi is still being disconnected successfully, and reconnected successfully
• updating ccmdb.mdb to .accdb; if that is the solution we will also need to update many scripts and VBS/VBA programs.
