'Minimum must not be infinity' in mosaiccing product generated by gpt.sh

Dear,

I have always used the gpt.sh tool to generate the mapped products in Ubuntu 16.04 (64bit). Recentlly, I found a problem that several mapped products presented dark images, though most of data are normal. Further, an exception was shown here when I used the RGB image to composite by the 'MODIS RHOS LOG' option (see attachments). The L2 file can be normmaly showed in SeaDAS, but the mapped data after mosaicing in gpt.sh were problematic, their minimums seem to be infinity according to the messeage of SeaDAS. The filename of L1A_LAC is A2008209061500.L1A_LAC, L2 product was generated from l2gen with a subset option config(27.65,100.73,27.76,100.85). The file of xml was attached.
I don't know why, and how to solve it? :cry:Could someone give me some suggestion?:grin:

Best Regards,

Could you please share your xml file?

I did l2gen on A2008209061500.L1B_LAC without using subsetting options. There is no data in the region (27.65,100.73,27.76,100.85), assuming (south, west, north, east). I was not able to do l2gen on A2008209061500.L1B_LAC with the given subset config.
