Can't add more than 30 Child Products

[9dotbox]

Joomla v3.4.1
VM v3.0.08

If I open a parent to edit it after I have added 30 child products, then click save, it goes to Virtuemart Dashboard and edits are NOT saved. I discovered this after creating 30 child products using Stockable Custom Fields plugin to add variants to the parent. When I went to create the 31st custom field, saving resulted in returning to the dashboard and 31st child was not created. It doesn't matter what I try to edit on the parent after it has 30 children, clicking save always results in returning to the dashboard without actually saving.

I have searched the forum for anyone with the same issue. I've seen suggestions about increasing the memory limit in php.ini, but this had no effect. I was able to get the remaining child products (total of 72) uploaded using CSV Improved, but if I ever need to make a change to the parent, I cannot without going through CSVI again.

Since I can get around this pretty easily with CSVI, this is a minor annoyance, but I'm concerned that this may cause other issues down the road if the root cause is not fixed. Any help is greatly appreciated.

You have a hidden config value maxChilds
in file JOOMLAROOT/administrator/components/com_virtuemart/virtuemart.cfg
see https://docs.virtuemart.net/manual/general-concepts/206-hidden-configurations.html
In this file, set/add for eg.
maxChilds=100
This should solve the problem
