我用Molclus 1.9.9.9版本调用xtb 6.5.0版本在GFN0-xtb级别下对包含主族金属的团簇的负离子体系进行几何优化任务时,曾多次遇到过对10个原子的团簇体系报错的情况,不论十个原子相同还是不同,也不论genmer产生的初猜结构好还是不好,而对其他数目的团簇体系并没有发现这种问题。具体报错的情况是,在命令行里执行了./molclus > out.txt &之后,命令行中紧接着会出现下面这种报错
*** Error in `xtbforrtl: severe (174): SIGSEGV, segmentation fault occurred

......
同时其他正在运行的xtb的任务也会变得非常慢,服务器此时甚至会卡顿,打开Molcus产生的out.txt文件查看发现,提示出现Cannot find .xtboptok file!这个错误,找不到.xtboptok这个文件,且每一个任务运行的时间极长(几十秒甚至上百秒),远比正常运行xtb时每个优化任务0~1秒要慢得多

请问大家有没有遇到过这种情况,出现这种情况是为什么,应该怎么解决?
谢谢大家!
