Difficult to say without a full reproducer.

I've just tested the below Python script with the 1.11 branch and FileGDB 1.4 
on Linux and it works fine:

from osgeo import ogr
from osgeo import osr

for i in range(10):
    ds = ogr.GetDriverByName('FileGDB').CreateDataSource('test%d.gdb'% i)
    srs = osr.SpatialReference()
    srs.ImportFromEPSG(4326)
    lyr = ds.CreateLayer('test', geom_type = ogr.wkbPoint, srs = srs)
    lyr.CreateField(ogr.FieldDefn('id', ogr.OFTInteger))
    f = ogr.Feature(lyr.GetLayerDefn())
    f['id'] = 1
    f.SetGeometry(ogr.CreateGeometryFromWkt('POINT (2 49)'))
    lyr.CreateFeature(f)
