PIO fatal error: Attached buffer is too small

[lxu16]

I tried to use the 22 nodes to run the E3SMv2 including the ChemUCI chemistry module. It seems fine for the 5-days test run. When I increase the simulation time to 1-month. The following errors come out when the program tries to output the restart file for the EAM component.

@dqwu may be able to help.

BTW, I used the compset "F20TR_chemUCI-Linozv3" and resolution is "ne30pg2_r05_oECv3". I also switch on the namelist for the UCI gas chemistry output.

history_chemdyg_summary = .true.
history_UCIgaschmbudget_2D = .true.
history_UCIgaschmbudget_2D_levels = .true.
history_gaschmbudget_2D = .true.
history_gaschmbudget_2D_levels = .true.

@lxu16 You can try increasing the default buffer size limit (64 MB) to 128 MB:
xmlchange PIO_BUFFER_SIZE_LIMIT=134217728

@dqwu Thanks for the suggestions! Now it works!
