GSI run time errors related to deallocation

Recently, I am working on GSIv3.7, then I encountered a weird problem. GSI exits with errors which are related to the deallocation of pointers.

When I tried to locate the source of errors, it traced back to the “obsdiags_reset” in the pcgsoi. Then I found out the problem occurred when it could NOT deallocate the arrays (or should I say the pointers) for the observations. Which makes it even more weird, the pointers could be deallocated for “PS” observation, but NOT for “T” and “U/V” observation.

Have you encountered these problems? do you have some ideas about why?

PS: the error message is like the following:

[036]m_obsLList::nodeDestroy_(): >>> ERROR <<< can not deallocate(node), stat = 173

[036]m_obsLList::nodeDestroy_(): >>> ERROR <<<                      %mytype() = "[tNode]"
